1. Incompatible Hardware:

The ‘CPU Does Not Support x86-64-v2’ problem happens because of hardware limits, especially with the CPU. The ‘x86-64-v2’ is an extra feature in the x86-64 system that makes CPUs work better.

If your CPU doesn’t have this feature and you try to use software that needs it, your CPU can’t do the necessary things, and you’ll get an error message.

2. Software Incompatibility:

If you see the ‘CPU Does Not Support x86-64-v2’ warning, it could be because the software you’re using is meant for a fancier CPU.

This happens when the program needs the ‘x86-64-v2’ feature, but your computer’s hardware doesn’t have it. It’s like a mismatch between what your computer can do and what the software needs.

3. Virtualization Issues:

In virtual setups, the computer pretends to have certain abilities to work with virtual systems. But sometimes, mistakes happen.

If you get the ‘CPU Does Not Support x86-64-v2’ issue in a virtual machine (VM), it could be because the virtualization software isn’t set up right.

Also, the main computer’s CPU needs to support ‘x86-64-v2’ for virtualization to work correctly.

Step By Step Procedure To Resolve The Error:

Step 1: Identifying Your CPU Model

Before we can solve the problem, it’s important to know what type of CPU you have. Follow these simple steps to find out:

Step 2: Open A Terminal Window.

  • Enter the command: sysctl -a | grep brand.
  • This will quickly show your CPU’s brand and model. Write down this information for reference.

  • In the VM settings, find the ‘System’ section and look at the ‘CPU’ configuration.
  • Look for your PC’s generation in the options. Choose the one with ‘V2’ in its title. For example, if you have a fifth-generation Intel Core Processor (Broadwell) without TSX, select ‘Intel Core Processor (Broadwell, no TSX) (Broadwell-v2).’
  • After selecting the right CPU configuration, save your settings.
  • Now, restart the Linux OS installation process.

Step 5: Testing the Solution

After you follow these steps, your Linux OS installation should continue smoothly without showing the “Fatal glibc error: CPU does not support x86-64-v2” message. Your CPU setup meets the requirements, making the installation easy and effective.
